Abstract (en)
[origin: EP0444480A1] In a process for the interpass cast-welding of finely perlitised rails by pouring aluminothermically produced steel into a casting mould surrounding the two rail ends, coolant is applied to the rail head surface of the rail sections adjoining the two casting mould halves after the molten steel has been poured in until the latter solidifies, in particular until the projecting weld material and the casting mould halves are sheared off. <??>A casting mould consisting of two mould halves for carrying out the process is also claimed, in which the mould halves (1) each have in the inner surfaces (2) facing the rail profile a groove (3) along their outer contour for receiving a sealing paste.
